Cockcroft–Gault
formula [22] |
Ccr = [(140 −age) × weight]/72 × Scr ×0.85 if the subject is female, in
milliliters per min |
MDRD study
equation [24] |
GFR = 175 × (standardized Scr)−1.154 × (age)−0.203 × 0.742 if the subject is
female × 1.212 if the subject is black, in milliliters per minute per 1.73 m2 |
CKD-EPI
equation [25] |
GFR =141 × min(Scr/κ, 1)α × max(Scr/κ, 1)-1.209 × 0.993Age × 1.018 if female ×
1.159 if black |
*where Scr is serum creatinine, κ is 0.7 for females and 0.9 for males, α is -0.329
for females and -
0.411 For males, min indicates the minimum of Scr/κ or 1, and max indicates the
maximum of Scr/κ or 1 |
